David Baas looking good

–Mike Singletary said he liked what he saw out of David Baas at center in the last game. If Baas continues to play well, he might be the one to replace Eric Heitmann while he recovers from a broken leg. Tony Wragge will get a look also in Sunday’s game.

David Baas is doing a good job stomping the competition.

–Alex Smith had a good practice, until he threw a pass intended for tight end Delanie Walker that Reggie Smith intercepted. Smith continues to look impressive and could challenge Michael Lewis for playing time. My guess is Smith will take his place on passing downs.

–Travis LaBoy returned to practice for the first time since the first week of training camp. He had been shelved by a concussion. LaBoy was in no mood to talk about his time off. “I don’t talk about injuries,” he said.

Smith, for one, wants to get Davis and Crabtree, presumably his main targets for the season, back in the huddle. When asked Wednesday about having the starters back, Smith said, “We’ve got to get the work in. If we just think we have these names or we’re going to show up on game day and get it done, that’s crazy, it’s totally crazy.”

-Nate Davis said he has three-quarters of the core plays down pat. Davis is also no longer playing with the gloves he used throughout his college career. “The main (reason for) not having gloves is the center sweats.” As gross as it sounds, it’s hard to throw with soggy gloves. Davis said all the centers (Heitmann, Baas, Wragge and Cody Wallace) are equal opportunity sweaters.

-Singletary was all over rookie linebacker NaVorro Bowman for looking at the quarterback, instead of covering a running back in a one-on-one drill.

-So where did Brandon Jones go on his first day after getting released by the 49ers? Seattle of course. Former 49ers GM Scot McCloughan signed Jones last off-season and is now a Seattle exec.
